If I love her daughter and she still wants one more kid, but I don't want anymore than her kid, is there still a chance?

I've never wanted kids of my own jewels, I've known that for years. But I'm dating someone who has a daughter and I already feel strong fatherly energy and love towards her. We're both 30.

We've known each other for awhile, but we're giving dating a chance since we connect so well to a spiritual/energetic level. We have so many similarities and get along super well.

The thing is she says she wants one more child, but I don't, and she knows that, but still she wants to keep trying and see if we are romantically compatible. We've slept together once before, a long time ago. We haven't been with others since we were last together, for a few years. We've talked about the idea of trying again on that as well and been flirty with each other.

Im trying to understand if it's possible we can fall in love, have a great relationship and decide that the three of us will be enough. I'm kinda scared to bring this up with her, specially now since we are still connecting and taking our time.

We're taking it very very slowly. We want to be sure of each other and that we're not hurting each other as well as for her daughter. Honestly I've never had anyone show interest in me the way she does. She was even the one to initiate all this with me
